I have to through Swell in the mix. I use it everyday. My pumps are great (I love seeing veins!!!) and my endurance in the gym is even better. It's got all the big boys - BA (1.6g), CM (1.0g), AAKG, leucine (3.0g) plus it has the Poseidon complex in it to keep you hydrated and help with capillary dilation and circulation.
